To @ZZ whom/it may concern: i

Beit' known that we, DANIEL S. KOONS and WILLIAM F. MOUGHLER, citizens of the Unitedv States, residing `at Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements inV Self-Cleansing Brushes; and we do hereby declare the following to 'be a full, clear, and exact description of the invention, such as will enable' others skilled in the art to which it appertains to make and use the same.

Our invention relates to a novel construction in a fountain bath-brush, the object being to provide a simple, durable, and efficient device of this character; rand it consists in the features of construction and combinations of parts hereinafter fully described and claimed. In the accompanying drawings, illustrating our invention, Figure l is a top plan view of a brush constructed in accordance with our Fig. 2 is a longitudinal section of same on the line 2 2 of Fig. l. Fig. 3 is a longitudinal section showing the application of the fountain devices to another form of brush. Fig. 4 is a detail sectional view, on an enlarged scale, of the valve shown in Figs. l and 2. Fig is a fragmentary bottom plan view showing the water-outlet from the brush.

Referring now to said drawings, A indicates a brush having a back C, in the middle or center of which is an opening l, and adjacent the ends is provided with recesses 2.' Said brush A is adapted to be secured to a false back B, which is provided with a central water-pasage 3, having a screw-threaded ope-ning or outlet 4, which is adapted to receive the hollow shank 5 of a screw 6, passing through said opening l in said back C, whereby the cesses 2 in said back C being adapted to receive dowels on said backB to hold these members rigidly in relative. position. The head of said screw 6 is provided with a plurality of radial passages communicating with the central passage in said shank 5 and form water-outlets. In this manner said screw 6 performs the double function of securing the back C to the back B and for connecting the water-passage in the back B with Athe brush proper. The flow ofwater to said brush is controlled by means of a valve 7,`havinga projecting stem 8, adapted to be operated by the linger to open said valve and admit water to the brush. Said valve is held normally closed bymeans of a spring 9 and also by the water-pressure, as will be obvious. Y

In brushes having a handle 1l the latter is made telescopic, rand to'thisend Vcomprises two members l2 and 13, the former of which is rigid with the back B and forms a continuation of the water-passage in said back I3',

, while the member 13 is of larger diameter and receives said member 12 and is telescopically movablethereon, a water-tight joint being effectedfbetween said members Yby means of a stuffing-box of ordinary construction, detailed description of which is omitted.

Said brush is connected with the water-supply by meansv of a flexible hose le, which is attached to a mouthpiece l5 on the brush or a similar mouthpiece. 16 on the handle 11, the inside diameter of the latter being sumciently large to permit the passage of the hose therethrough, so that the connection can be made directly with the brush, as shown in full lines, Fig. 2, or with the handle, as shown "in dottedlines in Fig. 2.

In'Fig. 3 we have illustrated a modified form of our brush, which likewise consists of a brush A', having a back C' and a false back B mounted thereon, the latter being hollow and provided with Va central waterpassage d, from the center of which an outlet b leads in the shape of an internally-screwthreaded pipe, which is adapted to receive the hollow stem of a nozzle c, which serves as a 'means for securing the backs B and C' together. At one end said back B is provided with a short hollow stem d, to which a hose e is adapted to be secured and from which said waterpassage ct" is adapted to befed. Between said steln CZ and the outlet b said waterpassage n, is provided with an annular shoulder f, which serves as a valve-seat for the valve g, the stem h of which passes through the con traction of said water-passage thus formed and through the other end of the back B'. A spring t' is interposed between 'the shoulder f anda collar j on said valvestein h and serves to hold said valve n or-y mally closed. Obviously by pressing thepro- IDO jecting end of said valve-stem inwardly said valve g will be opened and admit water to the portion of the passage d on the other side of said shoulder f. A strap 7.; :is securedl at the sides of said baok B' and passes over the latter, so that by inserting the hand betw'een said back B and said strap 7i: the brush can be firmly held and the fin gers at the saine time kept in position to operate the Valve.

IVe do not of course limit ourselves to the use of this brush for purposes of bath only, as it can obviously be advantageously used for other purposes.

IVe claim as our inventionl. In a bath-brush, the combination with a brush, and a false back adapted to be secu red thereto and provided with a water-passage, of a screw having a hollow shank anda radially-perforated head adapted to secure said brush to said false back and serve as an outlet for the Water in said Water-passage, substantially as described.

2. In a bath-brush, the combination with a brush, anda false back adapted to be secured A thereto and provided with a-Water-passage7 oi" a screw having a hollow shank and a radially-perforated head adapted to secure said brush to said false back and serve as an out- 'let for the Water in said Water-passage, means for connecting`- said Water passage with a source of supply of Water, and a Valve interposed in said connection, substantially as described.

3. In a bath-brush, the combination with a brush, and a false back adapted to be secured thereto and provided with a Water-passage, of a screw having a hollow shank and a radially-perforated head adapted to secure said 35 brush to said false back and serve as an outlet for the Water in said Water-passage, means for connecting said Water passage With a source of supply of Water, and a valve interposed in said connection, said Valve being on 4o
